【VSCode+SpringBoot】SpringBootでAPIを作る⑥

Posted at

前回↓

はじめに

今回はRepositoryを作っていきます

Repository作成

Repositoryはデータアクセスを抽象化し、オブジェクトの集合へ格納・取得・検索するかのような振る舞いを提供します
demo直下にrepositoryフォルダを作成してその中にPersonRepository.javaを作成します

src/main/java/com/example/demo/repository/PersonRepository.java
package com.example.springbootpostgresql.repository;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

import com.example.springbootpostgresql.model.Person;

@Repository
public interface PersonRepository extends JpaRepository<Person, Integer> {
    
}

✨解説

@Repository
データ層のクラスに付与します
データベースにアクセスするために定義します

おわりに

今回はRepositoryを作成しました
次回はServiceを作成したいと思います
